US 2020/0050012 A1 · LASER AIMING SYSTEM RECYCLING STRAY LIGHT

Abstract

A laser light projection apparatus is provided for projecting laser light onto the surface of a target object. The laser light projection apparatus includes a laser light source that generates laser light and a housing with a cavity therein defined by sidewalls, at least a portion of which have one or more reflective surfaces. The cavity extends along a center axis of the laser light and has a first portion at which a distance between opposing sidewalls is less than a distance between opposing sidewalls at a second portion of the cavity at a distance farther from the laser light source than the first portion. At least a portion of the laser light generated by the laser light source is reflected from the reflective surface of the sidewalls to form a two-dimensional pattern spaced apart from the center axis.

Dependent claims

A laser light projection apparatus, comprising:

a laser light source that generates laser light centered along a center axis;
and
a housing having an aperture from which the laser light generated by the laser light source is emitted and a cavity extending along a center axis of the laser light source and being defined at least in part by sidewalls at least a portion of which have a reflective surface, wherein the reflective surface of the sidewalls cause a portion of the laser light to be emitted from the aperture at angles divergent from the center axis, and at least part of said portion of the laser light emitted from the aperture forms a defined two-dimensional pattern spaced apart from the center axis.
